Abstract:
Objectives. This study explored young adults’ experiences of using e-health internetbased
computer or mobile phone applications (apps) and what they valued about those
apps.
Design and methods. A qualitative design was used. Semi-structured interviews were
conducted with a community sample of 19 young adults who had used a publicly available
phone or internet-based application. Transcripts were analysed using thematic analysis.
Results. Participants valued an attractive user interface. Structure, ease of use,
personalised features and accessibility (including dual phone-computer access) were all
important to participants and users indicated that continued use depended on these
design features. Many believed that a focus on calorie counting was too limiting. Some
users mentioned behaviour change strategies and known behaviour change techniques
utilised by apps including; self-monitoring, goal setting and behavioural feedback. Only a
few users reported positive changes in physical activity levels.
Conclusions. Use of particular design features and application of evidence-based
behaviour change techniques could optimise continued use and the effectiveness of
internet/smart phone interventions.
